Accomodate GUI for smaller, high-res screens

Hi,

After many years of strictly hardware music-making I stumbled upon AM. Watching the YouTube demos, I instantly knew that AM would be perfect for me; modular, non-linear, intuitive - yet deep. 

The very next day I put all my hardware stuff up for sale and bought a computer and AM (havent owned a computer for quite some years).

I ended up getting a 13,3" macbook air. While AM is running fine, the GUI is quite tiny on the high resolution 13,3" screen.

Input/output nodes and sliders (especially the halved sliders that are used to define intervals) are very hard to get right with the first click.

Hopefully, a future update could add some options to have the scaling of the GUI accomodate smaller, high resolution screens.
